General information
The liver is the central metabolic organ of the body.
Arterial supply
It is supplied via the hepatic artery (Arteria hepatica propria), which originates from the truncus coeliacus. The right branch (ramus dexter) of the hepatic artery also supplies the gallbladder artery (Arteria cystica), which supplies the gallbladder of the same name (vascular supply liver). The venous outflow of the gallbladder takes place via the gallbladder vein (vena cystica) into the portal vein system of the liver. The liver itself drains its venous blood into the inferior vena cava (lower vena cava) (vascular supply to the liver).
